ABSTRACT:
A portable envelope feeder that is not dedicated to a specific offset printer but can be used with multiple offset printers is described. The portable feeding apparatus is clamped to the feed elevator in order to supply an envelope stack to the offset printer. The envelope feeder has the capability of tilting back to facilitate loading of the envelope stack. A sliding weight in one of the vertical members holds the envelopes in place and also counters the moment created when the sucker foot on the printing press grips the individual envelope and pulls the envelope into the offset press. A height control bar insures that the envelope stack is always at the correct position for the sucker foot to grip and envelope. By utilizing a different size plate where the envelope stack rests and making a slight adjustment on the base plate, the present invention can feed a plurality of envelope sizes.
